Problem description:
Well, I've been thinking about converting PSe to 16x16 instead of the ugly and blocky 32x32 it uses now. However, I have absolutely no experience with developing anything with a 16x16 map.

I defined the icon_size and view. However, my grass turf is 64x64. The only map_format I can use without it be chopped into 16x16 bits is the TILED_ICON_MAP which still inflates everything and shrinks the mob icon.

Screenshots:This is what happens when I set the map format to TOPDOWN_MAP. The mob keeps most of it's quality(even so it's slightly inflated) and the grass tile is chopped up.
